Syntax:
|
FileOpenDlg (title, initial path, filter, check file exists, multi select)
|
|
Parameters:
|
title – The window title text.
initial path – The name of the initial path. This path will also accept the filename and show it in the dialog box. A blank value will use the last path chosen.
(Before version 1.9, this was: initial directory – The name and path of the initial directory. A blank value will use the last directory chosen.
filter – string. The filter string contains a description of the filter, followed by the vertical bar (|) and the filter pattern. The strings for different filtering options are separated by the vertical bar. Several filter patterns can be joined to a filter by separating the file types with semicolons. The first pair will be the default in the dialog box.
For example: 'Image Files (*.BMP;*.JPG;*.GIF) | *.BMP;*.JPG;*.GIF|All files (*.*)|*.*'
check file exists – This is a Logical type parameter that determines whether a warning message will be displayed if the user specifies a file name that does not exist.
multi select – This is a Logical type parameter that determines whether the dialog box supports multiple selections of files. In case this is True, the function will return those names delimited by a pipe ("|").
